    Each leg also has tube feet that can "smell" chemicals in the water alerting them to food or predators. When food is near, the tube feet become more active. Each tube foot has a suction cup at the end of it to help them grip surfaces, move along the seafloor or up glass. (5/7).

    At the end of each arm you'll notice a tiny red spot that looks like a tiny red fleck, but what you're actually seeing is its eye! That tiny red speck is the bat star's eyespot that is used to sense light and dark, but it is not a proper eye that can see images as we do. (4/7).

    Why does our bat star have six legs? We believe it sustained an injury many years ago before it journeyed to the museum, and instead of re-growing the one injured limb, it split into two. I mean, who couldn't use an extra arm sometimes? (3/7).

    Bat stars are cute & fuzzy because they're covered in gill-like structures that help them breathe. Like the rest of their sea star relatives, bat stars are capable of re-growing limbs. Most bat stars have 5 legs, but ours has 6 & some have been found with 9! (2/7).

    Meet the Exploratorium's resident bat star ⭐ Bat stars receive their names from the webbing between their short triangular legs that resembles a batwing, and while ours is a beautiful bubblegum pink, they come in a wide variety of colors. (1/7).

    Maria believed in the importance of the study of astronomy: “When we are chafed and fretted by small cares, a look at the stars will show us the littleness of our own interests”. (4/4).

    Did you know? This science activity is made possible by the contributions from astronomer and educator Maria Mitchell (1818 - 1889). Maria spent decades predicting how stars would move through the night sky and was one of the first women to discover a comet. (2/4).
